Abstract

A lawn mower comprising a frame, an engine mounted on the frame, a cutting mechanism driven by the engine constructed and arranged to cut grass and to generate grass clippings, a bag for collecting said grass clippings, and a bag-full indicating assembly. The bag-full indicating assembly includes an indicator that indicates to a mower operator that the bag is substantially full in response to a bag-full signal, and a switch which can be activated to generate the bag-full signal. The switch comprises a grass-contacting member extending into the bag. The grass-contacting member is movable from a non-activated state to an activated state by being displaced by grass clipping build-up within the bag. The switch thereby enables the bag-full signal for the indicator so that the indicator indicates to the mower operator that the bag is substantially full.

Claims

1. A lawn mower comprising:

a frame;

an engine mounted on said frame;

a cutting mechanism driven by said engine constructed and arranged to cut grass and to generate grass clippings;

a bag for collecting said grass clippings; and

a bag-full indicating assembly including an indicator that indicates to a mower operator that the bag is substantially full in response to a bag-full signal, and a switch which can be activated to generate said bag-full signal, said switch comprising a grass-contacting member extending into said bag, said grass-contacting member normally assuming a non-activated state and being moved from said non-activated state to an activated state by being displaced by grass clipping build-up within said bag, said switch thereby enabling said bag-full signal for said indicator so that said indicator indicates to the mower operator that the bag is substantially full;

said grass-contacting member comprises a flexible member being flexibly moved in response to a build-up of grass clippings within said bag, said flexible member comprising internal conductive contact members disposed in normally spaced non-conductive relation to one another, said conductive contact members being moved into conductive engagement with one another to activate said switch upon flexing of said flexible member to a predetermined extent upon build-up of the grass clippings in said bag.

2. A lawn mower according to claim 1, wherein said indicator is a visual indicator.

3. A lawn mower according to claim 1, wherein said indicator is an audio indicator.

4. The mower according to claim 1, wherein said mower comprises a chute communicating said cutting mechanism with said bag and providing a passage for said grass clippings to pass from said cutting mechanism to said bag, said chute having an outlet from which said grass clippings are received by said bag, said grass-contacting member having one end thereof fixed below said chute outlet and extending therefrom into said bag.

5. A lawn mower comprising:

a frame;

an engine mounted on said frame;

a cutting mechanism driven by said engine constructed and arranged to cut grass and to generate grass clippings;

a bag for collecting said grass clippings; and

a bag-full indicating assembly including an indicator that indicates to a mower operator that the bag is substantially full in response to a bag-full signal, and a switch which can be activated to generate said bag-full signal, said switch comprising an elongate flexible member extending into said bag, said elongate flexible member being in a normally substantially straight configuration and being flexibly bent in response to a build-up of grass clippings within said bag, said elongate flexible member comprising internal conductive contact members disposed in normally spaced non-conductive relation to one another, said conductive contact members being moved into conductive engagement with one another to activate said switch upon flexing of said elongate flexible member to predetermined extent upon build-up of grass clippings in said bag to thereby enable said bag-full signal for said indicator, so that said indicator indicates to the mower operator that the bag is substantially full.

6. The mower according to claim 5, wherein said mower comprises a chute communicating said cutting mechanism with said bag and providing a passage for said grass clippings to pass from said cutting mechanism to said bag, said chute having an outlet from which said grass clippings are received by said bag, said elongate flexible member having one end thereof fixed below said chute outlet and extending therefrom into said bag.

7. A lawn mower according to claim 5, wherein said indicator is a visual indicator.

8. A lawn mower according to claim 5, wherein said indicator is an audio indicator.

9. A ride-on lawn mower comprising:

a frame;

a seat mounted on said frame;

wheels mounted on said frame;

an engine mounted on said frame for driving said wheels;

a steering wheel mounted with respect to said frame for turning said wheels and steering said lawn mower;

a cutting assembly driven constructed and arranged to cut grass and to generate grass clippings;

a bag for collecting said grass clippings; and

a bag-full indicating assembly including an indicator that indicates to a mower operator that the bag is substantially full in response to a bag-full signal, and a switch which can be activated to generate said bag-full signal, said switch comprising a grass-contacting member extending into said bag, said grass-contacting member normally assuming a non-activated state and being moved from a non-activated state to an activated state by being displaced by grass clipping build-up within said bag, said switch thereby enable said bag-full signal for said indicator so that said indicator indicates to the mower operator that the bag is substantially full;

said grass-contacting member comprises a flexible member being flexibly moved in response to a build-up of grass clippings within said bag, said flexible member comprising internal conductive contact members disposed in normally spaced non-conductive relation to one another, said conductive contact members being moved into conductive engagement with one another to activate said switch upon flexing of said flexible member to a predetermined extent upon build-up of the grass clippings in said bag.

10. A ride-on lawn mower according to claim 9, wherein said indicator is a visual indicator.

11. A ride-on lawn mower according to claim 9, wherein said indicator is an audio indicator.

12. The ride-on lawn mower according to claim 9, wherein said mower comprises a chute communicating said cutting mechanism with said bag and providing a passage for said grass clippings to pass from said cutting mechanism to said bag, said chute having an outlet from which said grass clippings are received by said bag, said grass-contacting member having one end thereof fixed below said chute outlet and extending therefrom into said bag.
